Engine Idling High

Rionna · 05-20-2011, 09:35 PM

Hi All,

First ride on my 2009 GZ250 today. It had one mile on it. Question when I disengage the clutch the engine idles high and loud. It sounds as if I am opening the throttle, but my hands aren't even touching the throttle. Is this just a break-in period issue, or should I take the bike to have it serviced. I am concerned about damaging the engine because it sounds as if I am revving the engine and the manual said not to do that until after 500 miles. Thanks in advance for your advice.

Make sure your choke is turned all the way off.(pushed all the way forward.) If it is pushed all the way forward,(bike warm)you can turn the idle down with the white plastic knob on the bottom of the carb.Idle should be around 1200 RPM.
Also you will want to adjust the shifter & brake pedal to where they are comfortable for you.

:cool:

Thank you so much! I was worried I would have to take it in for service. This is an awesome site.

You were right, the idle was set to high. A little turn of the white knob, and it now sounds great. I'll get more familiar with my friction zone and practice my turns tomorrow. The revving was interfering with my learning the friction zone. Thanks again!

In case you're not sure - The brake pedal should be adjusted so that it's just UNDER your foot when you're sitting comfortably. For some reason they ALL come from the factory set up wrong. Don't forget, once you've moved the pedal (by way of the bolt that's underneath it) you'll need to adjust the brake light switch, by turning the barrel (under the bike). All this is really easy, even if you're not mechanically inclined, & you'll start to learn about your bike. :2tup:

To reinforce what Blaine said, adjust the idle speed only after the engine has warmed up to proper operating temperature.
